keelvlek

Keelvlek is a Dutch term that describes discoloration observed on the mucous membranes of the throat. It is a descriptive finding rather than a formal disease name and is used by clinicians to note an area of visible staining or pigment_change in the oropharynx, including the soft palate, tonsillar area, or the uvula. The color can range from red or pink to brown or yellowish, and the appearance may be static or transient.

Causes of keelvlek are varied and non-specific. They can include transient stains from foods and drinks such as coffee, tea, red wine, beet juice, or certain spices. Medications or supplements that discolor mucosa, smoking-related irritation, dehydration, or simple mucosal irritation from minor trauma can also produce a keelvlek. Less commonly, infections or inflammatory conditions may alter the coloration of the throat mucosa. Because keelvlek is a non-specific finding, it must be distinguished from mucosal ulcers, exudates, or pigmented lesions that may require further evaluation.

Diagnosis is clinical, based on direct inspection and patient history. If the discoloration persists, is accompanied by symptoms such as sore throat, fever, swelling, or lesions that do not improve, a clinician may perform additional assessment, including a thorough ENT examination and, if indicated, laboratory tests.

Management depends on the underlying cause. Removing the triggering factor (dietary stains, smoking, dehydration) often leads to resolution, while persistent or atypical discoloration warrants medical review. The term keelvlek itself reflects its etymology from Dutch keel (throat) and vlek (stain).
